Product Description:

The MAC090A-0-RD-4-C/110-A-1/WI525LV/S001 AC Servo Motor offers reliable motion control with compact design and integrated feedback systems. The motor delivers stable performance in dynamic and static operating conditions. It supports controlled stopping and secure hold at rest.

The MAC090A-0-RD-4-C/110-A-1/WI525LV/S001 AC servo motor provides a continuous torque of 3.5 Nm at standstill. It draws a continuous current of 11.4 A under these conditions. The torque constant is rated at 0.34 Nm/A at 20 °C. Rotor moment of inertia of the servo motor is specified at 20 × 10⁻⁴ kgm². These values allow for fast dynamic response and precise control. The feedback system includes tacho feedback along with an optional incremental or absolute encoder. This setup supports accurate position and speed regulation. The motor is suitable for applications requiring consistent performance such as CNC systems, robotics and automated machinery. The motor frame construction ensures effective heat dissipation during long duty cycles. It handles repeated acceleration and deceleration efficiently which is essential for precision controlled equipment. Motor temperature is continuously monitored using thermal switches embedded within the MAC series AC servo motor windings and mounted on the stator housing. These thermos protective devices detect abnormal temperature rise and trigger a protective response.

The Bosch Rexroth MAC090A-0-RD-4-C/110-A-1/WI525LV/S001 AC servo motor also features a standard holding brake. This brake uses an electrically actuated release mechanism. When power is removed, the brake engages automatically. It provides a holding torque of 6.5 Nm that ensures mechanical stability during inactivity. The release delay time is measured at 60 milliseconds. The clamping delay is 20 milliseconds. The braking system enhances reliability during power loss or emergency stop conditions. It maintains position without drift or back driving.
